Safety Communicator (SC) is an app for both industrial-grade and non-industrial-grade smartphones. Available for both Android and iOS phones, it enables real-time communication between a worker’s personal safety instruments and a remote monitoring system. The phone and app act as a personal communication hub for a worker, which collects instrument readings and alarms from instruments over Bluetooth (BLE) or Wi-Fi and transmits in real time to a remote system over a 3G/4G cellular communication network. To further promote worker safety, the app also transmits a worker’s information and location to the remote system, which allows safety managers to quickly react and provide necessary assistance in case of an emergency.
